Default Best Cone Replacement For National Style 0

Recently I had my friend and his little kid over for a visit. To make a long story short the kid managed to get into my studio and somehow apparently whilst spinning around on my studio chair he slipped off the chair and landed on my National Style O. The result being that he pushed the cover plate in and broke the cone. The cover plate popped back out but the cone has had it.

Is a cone replacement a specialist job to install and set up or can I do it myself??

And what are the best cone replacements for the Style O??

Any help would be greatly appreciated.

Thanks

The best cone for a National -would come from National.

there is really only one choice for this...

https://www.nationalguitars.com/prod...cuit-resonator

and it is a pretty easy job.

strings off
remove cover plate
pull out speaker
remove biscuit from speaker (1 phillips screw)
put biscuit on new speaker
put new speaker in reso
put coverplate back on
new strings

when putting the strings back on I've found personally stringing in this order seems to align the cone the best (low E, high E, A, B, G, D). If the cone is buzzing when restrung to pitch, loosen the strings, and try and center the cone by moving the biscuit.

Copy/pasted from the FAQs at National's web site:

Can I install a new cone myself?

The new alloy cones are direct replacements for both vintage and new National guitars. For Tricone guitars, the installation is usually very simple. Remove the strings, tailpiece, and coverplate. Next, remove the aluminum T-bridge and the old cones. Place the new cones in the soundwell and reinstall the T-bridge. Make sure to carefully align the 3 pins of the T-bridge with the small holes at the apex of each cone.


The single cone installation is a bit more involved. Our new alloy 9.5” cone sits .080 inches lower than the previous generation (1999-2007), a new biscuit saddle is necessary and included with the purchase of a new 9.5” cone. The biscuit will need to be cut and slotted for setup. Please visithttp://littlebrotherblues.com/Gear/National-EN-Setup/index.html for a tutorial on cutting a new saddle. If you do not have the proper tools for the installation, take your instrument to a qualified repair person

I would take the guitar to a shop where they can take care of your problem. There are a number of things that can cause you trouble if you are not use to working on this type of guitar.

You might run into an issue with the biscuit saddle not being the correct height and have to cut a new saddle at the correct height and that can be fiddly if you haven't done it before and need to do it, you can always get two saddles and rough cut one and then transfer the profile to a second. I found cutting the new saddle the most labor intensive and the part requiring luthier's tools.

If you note or mark the locations of everything and are careful not to strip the screws, I don't think you would have much trouble reassembling it.

Another thing I found there is get the location of the tailpiece and its angle correct as the strings can align to it and no matter if you center the saddle or not if the tailpiece is angled it most likely will steer the biscuit into alignment with it.

Good luck.
